Using these Wahoo RPM sensors is easy. First, find a good spot on your bike to mount the sensors. You can put the speed sensor on the fork or the chainstay, and the cadence sensor on the crank arm. It's like sticking a little gadget in place, no complex tools needed. Once they're on, turn on the Bluetooth or ANT+ on your smartphone or bike computer. Search for the sensors in the device's settings and pair them up. Now you're ready to hit the road and see your cycling data. When it comes to maintenance, keep the sensors clean. You can use a soft, dry cloth to wipe them down after a ride, especially if they got dirty or wet. Avoid using harsh chemicals. Also, make sure to keep the battery in good shape. If the sensors stop working properly, check if the battery needs to be replaced. And that's it! You're all set to enjoy your cycling with these handy sensors.
